Drive unitWith VA Tekniks replacement drive unit you can combine the better of two worlds.Simplify maintenance and reduce the environmental impact.In many cases the tank insides has been refurbished without replacing the old greasy drive units.
UsageFor tanks with modern sludge scrapers but old drive units.
ExecutionMotor and gear mounted on a plate made of hot-galvanised steel with threaded rods for chain tensioning. Sprockets adapted for the gearing needed for the drive shaft’s sprocket. The minimum dimensions for the area necessary to change operation are 100 mm wide by 500 mm long, recessed or surface operation. EconomyA change to plastic chain operation along with a new driveshaft means that cutting down the driveshaft belongs to the past.You can easily change sprockets without un-mounting the driveshaft.You get rid of oil and other lubricants, you gain in increased lifetime, you make less environmental impact and you decrease your power consumption.
Advantages• No oil leakage• Less spare parts• More physical space around tanks• Decreased power consumption• Water lubricates the chain• Tanks are isolated from each other (when double-tanks)• Plastic chain has longer lifetime
The maintenance of sludge scrapers mostly attends to take care of machines mechanically, chain tensioning and to grease chains and bearings. Often there is oil escape which increases wearing on roller chain and sprockets.
The wearing also increases cost of maintenance, in worst case there will be a major failure.
